Where can I find the story of the bored King about 1 grain of wheat on the first square of the Chessboard, 2 grains on the second, 4 on the third and so on?

Thanks.

Dear viewer,

The story goes like this:

In an ancient Kingdom, a brave and mighty King in India named Kaid who had fought in many wars and won them all, had built a huge empire 1500 years ago, and after having accomplished all he wanted in life, found himself very bored.

The King sent out a proclamation to all his domains and lands that whosoever could relieve him of his boredom would be granted anything he wanted in his Kingdom. The word spreaded out quickly and people from all lands showed up and tried to relieve the King's boredom. Poets, Jugglers, Philosophers, Acrobats, Clowns, Dancers, and Jesters, all tried to interest the sullen King. But to no avail, the King remained very bored.

His Minister Sassa hereupon bethought himself of a rare game, the invention of an ancient Grecian sage named Hermes, which had recently been introduced into India by Alexander and his soldiers, who used to play it at times of leisure.

Sassa procured and modified the game and board from 112 squares and 56 pieces to 64 squares and 32 pieces and explained it to the King who played it with both satisfaction and delight, finding the game so amazing and a perfect substitute for war, that he was a happy man again. Soon the whole court was playing the game for hours.

The King asked Sassa: “How can I reward you? Gold or Jewels? Perhaps you want to marry one of my daughters? Choose anything you like.” Sassa replied
“Your Majesty, all I ask for is this: put 1 grain of wheat on
the first square of the board, 2 grains on the second square, 4
grains on the third square, and continue to double the grain on
each square until all 64 squares have grain.”

They all wondered at how this silly Minister was, since he only wanted a few grains of wheat after winning such a prize. The King Kaid at first thought he'd gotten off easy and readily agrees.

First the King's Ministers sent for a few stalks of grain, then they sent for a few buckets of grain, then they sent for a few bushels of grain and then... they sent for a few fields of grain!! After that, they sent for a Mathematician. The Mathematician told the Ministers and the King that the amount of wheat that Sassa requested would take all of the wheat in the entire world!

The King immediately sent for the Minister Sassa. When the King asked him why he had done such a thing knowing that the King could not possibly fulfill the request, Sassa answered him with a story: "One day while your highness was coming home from the wars you came upon a man who you had heard was wise. You asked him to tell you the meaning of life. You said that you had not a lot of time because the business of the state had taken all your time.

He bent down to the ground and picked up a grain of wheat and holding it in his hands, held it up to you and said: All of life mysteries, intrigues and adventures were found in a grain of wheat. You were very angry because you thought that wise man had wasted your time. I was that man. I did not want the wheat I just wanted to teach you a lesson."

The King and the Minister laughed together and became good friends. They played Chess together almost every night until the end of their days.

Now, if you like to know how much grains of wheat it would have actually been, here they are:
